1.7.11 APSCM

1.7.11 APSCM
The APS Channel Mismatch alarm occurs when the ONS 15310-CL or ONS 15310-MA expects a
working channel but receives a protect channel. In many cases, the working and protect channels are
crossed and the protect channel is active. If the fibers are crossed and the working line is active, the alarm
does not occur. The APSCM alarm occurs only on the system when bidirectional protection is used on
OC-N ports in a 1+1 protection group configuration. The APSCM alarm does not occur in an optimized
1+1 protection configuration.
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Warning
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of
100 mm could pose an eye hazard. Statement 1056
Use of controls, adjustments, or performing procedures other than those specified could result in
Warning
hazardous radiation exposure. Statement 1057
